Title: Control device for suspension mechanism
Inventor: INOUE NOBUAKI
IPC: B60G17/015
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To suppress unsprung vibration relating to a specific road surface input, by reversing damping characteristics in an extending/ contracting direction of a hydraulic shock absorber when the unsprung vibration is generated during running at a car speed of prescribed value or more based on a car speed sensor and a running condition sensor. SOLUTION: A damping characteristic of each hydraulic shock absorber A is controlled by an output of an electronic control device 35 based on each signal of an acceleration sensor 43 and a car speed sensor 23. When unspring part resonance is generated during running at a car speed of prescribed value or more, damping characteristics in extending/contracting directions of the hydraulic shock absorber A are reversed. That is, a change rate of damping force relating to a piston speed of the hydraulic shock absorber A is decreased in an extending direction and increased in a contracting direction, relating to a regular repeated road surface input of a free way hop or the like. In this way, a pattern of the unspring resonance generated by a continuously received vertical vibration input is changed, so as to suppress the unsprung vibration.

Title: Manufacture of forging work roll for hot rolling
Inventor: GOTO HIROSHI
IPC: B21B27/00
Filed: 1992-12-04
Abstract: PURPOSE:To eliminate the need for repeated reheating and to improve the working efficiency by carrying out constant temperature forging to a necessary part of a forged steel work roll material for hot rolling as it is heated at a prescribed temperature range and the temperature is maintained. CONSTITUTION:When roll material containing many alloys and inferior in hot forgeability is manufactured, it is forged as the heating temperature of a necessary part of the roll material is maintained by a low frequency induction furnace at 1050-1150 deg.C. Further, when the constant forging temperature is lower than 1050 deg.C, deformation resistance becomes large and, on one hand, when it exceeds 1150 deg.C, partial melting is followed to lose a forging effect. In this way, the need for reheating in the time of forging is eliminated, or, the frequency of reheating can be reduced and hot forging work can be performed effectually.
